My ex can't eat grapefruit, and avoids the flavor in drinks, etc., because of a drug interaction on the list for something he takes twice a day.

Looking on Amazon I found bulk Psyllium Husk, but I buy it in small gelatin capsules. The prices have gone up drastically lately and I just looked at the most recently purchased bottle - there is a lack of information about the actual volume of psyllium in the dose of 5 capsules. Looking at the name-brand products offered at Costco (bulk purchasing) the product with sugar and flavor adds up to 90 calories, and the non-sugar one uses Nutrasweet (Aspartame) that I'm allergic to (causes diarrhea). I imagine using unflavored bulk psyllium in a smoothie would be good (I add gelatin for the nail-strengthening properties) but I don't have a smoothie every day. The prospect of a chronic problem with sticky drinking glasses doesn't appeal, but lowering the price per dose does. I will look into it.

Spinoff of Mrrzy's interesting times is that the rest of us can reexamine how we are going about self-care.
